'SPECIFICATION forming part of Letters Patent No. 455,360, dated July 7, 1891. Application filed .Tune 26. 1890. Serial No. 356.775. (No model.) y

To all whom it may concern:

' Be it known that I, FERDINAND RocHow, a subject of the Emperor of Germany, and a resident of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Station- Indicators, of which the following is a specilication.

` My invention has for its object the auto- Io matic indication by means of an indicator in which rolls having printed or otherwise produced upon their exposed surface the names of the stations and which is to be placed conspicuously in a car or other vehicle of the i5 station to which said vehicle is. approaching,

either as it departs from or arrives at a station on the line, as may be desired, and for other purposes of `like nature to which itmay be advantageously applied. zo My invention essentially consists of the combination of two specific devices, each separate device havingr its own sub-combinations, and therefore, for the better identification of such specific devices, I shall in the following description term them, respectively, the

striking and indicator-operating mechanism, and as such they will be known in the description and claims.

In my application filed January 9, 1890, Serial No. 336,441, will be found a full, clear, and exact description of my station-indicator, to which reference is hereby made.

In this specification I shall describe and claim the mechanism used to operate the rolls i 3 5 upon which the names of the stations are produced. This mechanism is by me termed the indicator-operating mechanism. I attain the before-mentioned objects by the mechanisms herein described and claimed, andpfur- 4o ther illustrated by the accompanying drawings, lforming part of this specificatiomnin which- Figure l is a transverse cross-section through the indicator, showing the indicator-l operating mechanism in section and a portion of the ends of the indicator-rolls; Fig. 2, a, like view on the line 5 6, Fig. l; Fig. 3, a front elevation of the pawl and ratchet and detent of the indicator-operating mechanism; I5o Fig. 4, a view, partly in section, taken on the line 7 8, Fig. 3; Fig. 5, a plan view lof a dewheels.

'the vcase H2 is provided with bearings CZ d,

through which a spindle I is passed and which is free to turn therein. Upon this spindle is rigidly and preferably centrally aflixed a detentwheel J, having radial teeth J with segy 7o'- mental surfaces ori-their ends, which serves both for the purpose of holding the rolls in the position assumed after their operation and for actuating them. Directly above the bearings d d are bearings e e, in which are mounted to ro- 7,5 tatespindlesKK,thespindleKbeingsquared,

as at f, for engagement with a key, as will be hereinafter set forth. Upon the spindles K K are rotatably mounted two wheels I. L', having outwardly-extending lugs m2 m3, carrying 8o. pawls g g', and which will be called pawl The pawl-wheels have the peripheral grooves M2 M3, in which the chain G rests. Upon the same spindles are rigidly secured by pins 7i h two wheels M M', which 85 have ratchets fi t, which are inclined inwardly and are concentric with thev periphery of its respective wheel, formed withintheir inner peripheries for engagement with the pawls, and which will be called ,.Fratchet- 9o wh eels. There are two ratchets, formed diametrically opposite each other, on eachwheel. The ratchet-wheels or the pawl-wheels are provided with hubs jj', which serve to keepthem the requisite distance apart. The spindles K and K', carrying the pawl and ratchet wheels, are united together by the pins lo lo', which not only lserve;to unite the two sets of pawl and ratchet wheelsinto one integral system, but act intermittently as the roo detent and roll-propelling mechanism, and they will be hereafter known as the detent-.-'

Located atany convenient place, either on the case H2 or on the spindle I, are two deflectors N N', used for detlecting the pawls g and g' out of contact with the corresponding ratchets, and having an inclined surface Z, Fig. l, upon which the arms m and m' of the pawls slide, the said arms when moving over the deflectOr-surface withdrawing the pawl from its ratchet against the pressure of a spring fn. n', located on the pawl-wheels.

In combination with the last-stated arrangement the following may be used, thus insuring absolute certainty of operation and relieving the parts of undue strain: On the walls of the easel-I2, Fig. 5,' are produced stops o o', (but one set being shown,) which are intended to engage like stops p p' (but one set being shown) on the pawl-wheel and prevent, in conjunction with a like engagement of the arms m fm' of the pawls with the stops q q', Fig. 4, on the v deflectors N. N', the farther rotation of the pawl-wheels in the direction opposite to that in which the indicator-rolls are being moved.

'Instead of the foregoing arrangement of stops and deiiectors being used, I can use separately that shown in Fig. 5, in which but oneV set of pawl and ratchet wheels is shown. In this modiiication it will be seen that the construction of the pawl and ratchet wheels is the same, and that the stops 0' and p' are used in the same manner as before set forth, but instead of using the detlectors before shown and described a deflector constructed as here shown at o", fastened to the wall H2, may be used. It is provided with an inclinedface frz, byA which the pawl is removed from the ratchet. Instead of the arm -fm' of the pawl being used to assist the stopso p' in arresting the motion of the pawl-wheel, as before described, the stops lo' and p' may be set in advance in relation to the deiector v" and arm m', sor that the rotation of the pawl-wheel will be entirely arrested before the deflector and arm m' come together, thus relieving the pawl of any undue strain.

The linked chains G G', Fig. l, pass up into` the car from the striking mechanism over the pulleys c c, then through the slots.

V V' in the ease H2, around the ratchetwheels L L', to which they are rigidly secured by the4 pin w, Fig. 2, thence out through the same slots, and are linked to the retractingsprings V' V2, Fig. l, which are held at one end by brackets w' wz. placed in the linked chain G' to adj ust its length. By this means the striking and indicator-operatin g mechanism are operatively connected.

The indicator operating mechanism and the indicator-rolls are connected in the following manner: On the end of the shaft I of the indicator-operating mechanism is rigidly secured the large bevel gear-wheel WV, which meshes with. the smaller bevel-pinionZ on the shaftOof the upper indicator-rolls, and in this Way the indicator-operating mechanism Turn-buckles V3 are and the indicator-rolls are operatively .connected together. The ratchet-wheels M M require two operations in order to give them a complete revolution, the deteiit-wlieel J' eight. The gear V makes one revolution to f two of the pinion Z. This movement of the chain, which passes around the pawl-wheels and is fastened to them at w, Fig. 2, gives the pawl-wheels one-half a revolution, and in turning, the pawls being freed from the detlectors N or r', Figs. 4 and 5, are forced by the springs n on the pawl-wheels into the ratchet 'i in the ratchet-wlieel, carrying the ratchetwheel with it, thereby giving it one-half a revolution. connected together by the pins 7c 7c', both ratchet-wheels and but one pawl-wheel move together, the pawl-wheel which the chain G' does not rotate by reason of its not having The two ratchet-wheels being been actuated byits respective striking-lever coming in contact with the projection on the track being held in its normal position (it being loose on its shaft) by the springs V'. The release of the striking-lever from the block C and the recoil of the striking mechanism releases the strain on the retractingsprings V',which-then retract and rotate the pawl-wheels in a direction oppositek to thatA which they previously had been moved. This return rotation of the pawl-wheels brings the stops o and p or the arm on on the pawl and stops q in contact, thereby arrestin the further rotation of the latter mechanism. At the same time the armfm on the pawl passes over the inclin ed deflector-surface Z or r2, and thereby re-:

moves the pawl from contact with its ratchet. In Fig. 5 the stops o' p' arrest the motion of the mechanism before the arm m cornesin con.-

tact with the deflector r', and, as before-stated,

the same can be done in the other arrangement.v

There being two ratchets on each ratchetwheel diametrically opposite each other, so that as the wheel makes one-half turn each time it is operated a ratchet will be presented in the proper position for co-operation with its respective pawl. and-ratchet :system brings the pins 7a 7c' in contact with the segmental surface of the teeth J' of the detent-wheel J, and as. the pin k moves farther into the space between the respective teeth J' it rotates the detent-wheel J in the opposite direction, and before the pin 7c has entirely left the segmental surface opposite to that which Ithe pin 7a is Operating on and on the sametooth. the pin k has entered the space between that` toot-h and the one following it, thus locking the mechanism and holding it until the pin k' has rotated. and entered another space between the teeth,
